2 Claims. (Cl. 15- 51) This invention relates to improvements in electrically operated floor mops.

An object of my invention is to provide a device of the kind characterized in which is embodied an endless floor mop having novel electrical operating mechanism associated therewith.

Another object of my invention is to provide an electrically operated floor mop having novel roller means, conveniently controlled by a lever on the handle, for causing excessive quantities of water to be pressed therefrom.

A further object of my invention is to provide a device of the kind characterized, embodying adjustable means for regulating and providing the proper tension on an endless mop which is adapted to be operated over a floor surface by electrically actuated mechanism.

Other objects more or less apparent will present themselves or will be specifically pointed out in the description to follow.

In the accompanying drawings: Fig. l is a vertical longitudinal sectional view of an electrically operated floor mop constructed in accordance with my Fig. 2 is a horizontal proved floor mop;

Fig. 3 is a sectional of Fig. l;

invention; sectional view of my imview taken on the line 3--3 Fig. 4 is a front view of the roller means employed to squeeze excess water from the endless Fig. 5 is a side view showing the adjustable of a portion of the device,

and detachable means for mounting one of the rollers over which the end- ;less mop extends.

Fig. 6 is a sectional view taken on of Fi 5;

the line 6-6 Fig. '7 is a sectional view taken on the line 7-7 of Fig. 2;

Fig. 8 is a. side view of a portion of the device,

showing the detachable means mounting the axle of the other roller over which the mop extends.

Referring to endless the drawings a suitably shaped wall or panel 3 and a block 6 bolted to the a top cover 4.

Mounted in side wall 2, in close proximity to the bottom edge thereof, is the axle 5 jof a roller 5.

posite end in a similar by suitable bolts the side wall 1.

The axle 5' is mounted at its opblock 6 which is secured within an opening provided in Rotatably mounted at its ends within adjustable plates '7 which are secured in place by suitable bolts w ithin slots and guides provided in the side walls 1 and 2, is the axle 8' of a roller 8. Also rotatably mounted at its ends in the adjustable plates. '7, is the axle 9' of a cleaning device or roller 9. The cleaning device 9 is positioned in front of the roller 8, and sprockets 8a and 9a secured respectively to axles 8' and 9 over which extends. a chain 10, serve as means for causing the rotation of the brush 9 when the roller 8 is rotated. Extending over the rollers 5 and 8 is an endless. mop 11, made preferably from a suitable cloth material. Also extending over the rollers 5 and 8 are. endless rubber bands 12, which tend to serve as additional means for transmitting rotary motion from the roller 5 to the roller 8. i 7o In order to provide convenient means for adjusting the relative positionsof the-rollers 5 and- 8 so as to maintain a proper tension on the endless mop 11, I have provided a pair of set screws 13 at the front end of the frame. The set screws loosely extend through the cover 4 of the frame and screw into the plates 7. When the bolts. which normally maintain the plates 7 in their fixed positions are unloosened, the set screws may be manipulated to move the saidplates either backwardly or forwardly to thereby cause the roller 8 to be moved toward or away from the roller 5. The proper adjustment of the roller 8 with reference to the roller 5 causes the proper tension to be applied to the endless mop l1.

Secured as by screws to the rear side 3 of the frame is an electric motor 14 which has a pivoted bracket 15 affixed thereto for supporting purposes. The bracket 15 carries a roller 16 which enables the device to be conveniently shifted as it is propelled over a floor surface. A tubular handle 17 is pivotally attached by means of a yoke 18 to the motor 14, and supporting bars 19 aflixed to the said motor serve to provide a back rest or a prop for the handle. The motor is suitably connected by wires 20 to a switch 21 provided at the upper end of the handle.

The motor shaft is provided at its forward end with a worm gear 22 which meshes with a gear 23 secured on a shaft 24. The shaft 24 is rotatably mounted on suitable supports secured to the frame, and a sprocket 25 also secured to the said shaft is caused to rotate when the motor is operating. The axle 5 of the roller 5 is provided with a sprocket 26, and an endless chain 27 extending over the sprockets 25 and 26 serves to transmit rotary motion from 25 to 26, thereby causing the roller 5 to be rotated. The rotation of the roller 5 in a counter-clockwise direction causes the endless mop 11 to be actuated in such mersed in a cleansing bath, I have provided a mu:

er 28 and actuating means therefor which enables the said roller 28 to be firmly forced to ward the roller 5 and against theni'opwhilethe said mop is being actuated over the said roller 5 The axle of the roller 28 is rotatably hung at ends of side bars 29. The opposite ends of theside bars 29 are rigidly secured to a cross rod 30 which is rotatably mounted on supports 31 secured to ther'ea'r side'3 of the frame. A lever 32 is rigidly secured to the cross rod 30, and a wire 33, extending. th'rougha tubular covering 34' leading to the handle 17,-connectsIthe lever 32 with a manipulating lever.35 located at the upper end of the handles By pulling the manipulating member 35 upwardly the roller 28 ismoved toward the roller 5iand against the mop 11, thereby permitting excess; quantities of. water to be pressed from the said mop as itis being actuated over its associated rollers. a I

It is to be noted that the mop may be removed fromits rollersfi and 8 by removing the retaining boltsfrom the sidewall '1 of the frame and allowing the block 6 and plate 7 located in the said side walljt'o be detached. The rollers 5 and 8 when" not supported by the detached plateand blockfare allowed to be removed from the frame, thereby enabling the endless mop to be taken from :3 the'said rollers, and replaced if so desired.

lI n.operation, while the motor is causing the movement of themop over its associated rollers, the apparatus is moved over the floor to be cleaned ojrfdried, whereupo'nthe cleaning device or roller9 operates tojclean the surface, moving the dirt or moisture rearwardly to be later gathered by the mop.

If it is so desired, the front end of the frame may be constructed in such a manner that the front brush 9 is permitted to come directly in contact with the corners and side walls of a room. There are various other changes possible in regard to such details of construction as those which concern the means for adjusting the relative positionsof the various rollers, the means for transmitting motion from the motor to the endless mop,

and the shape and construction of the frame. It is therefore to be understood that the claims are to be considered as defining the scope of my invention rather than the exact construction shown on the drawings.

Having described my invention what I claim is: i-. In a mop, a frame, a pair of spaced rollers mounted in said frame, electrically operated means for'rotating one of the rollers, an endless mop extending over the rollers in contact with a supporting surface, means for adjusting the. position of one of the rollers, whereby the tension on the mop may-be regulated, a third roller supported ,on the frame and normally located adjacent to but in parallel spaced relation with respect to one of the first mentioned rollers, means for moving the saidthird roller toward its said ad-. jacent first mentioned roller, whereby the said third roller may be broughtinto contact with. the mop, and a manually'operated lever for actuating the said means.

2. In a mop, a frame having side walls and a rear wall, a pair of spacedrollers mounted between the side walls, an endless mop extending over the, rollersand adapted to contact with a supporting surface, an electric motor, secured to and extending rearwardly from the rear wall of the frame, a caster secured to the motor and adapted to engage with the supporting surface, means operatively connecting the motor and one .of the rollers, a handle pivotally attached to the motor, means for pressing water from the mop, and a manipulating lever on the handlefor operating the said means.
